Abstract

The invention discloses a wire rod laser flying code printing device, a laser code printing system and a wire rod production device.The wire rod production device comprises a wire drawing device and a wire rod laser flying code printing device, the wire drawing device is used for pulling a wire rod to move, and the wire rod laser flying code printing device comprises a laser assembly and a stabilizing assembly; the laser assembly comprises a laser device with the peak frequency larger than or equal to 120 KHz, a galvanometer with the scanning speed larger than or equal to 12000 mm / s and a field lens, the galvanometer is installed on the laser device, and the field lens is connected with the galvanometer. The stabilizing assembly is provided with a wire guide groove, the wire guide groove is used for allowing the wire to penetrate through and limiting the wire in the radial direction so as to keep the wire stable, the stabilizing assembly is provided with a code printing station, and the code printing station is located on the wire guide groove. Wherein the laser device generates laser, and the laser sequentially passes through the galvanometer and the field lens and irradiates the code printing station. According to the technical scheme, long character fields can be printed under high-speed transmission of the wire rod.

Description

technical field [0001] The invention relates to the technical field of laser marking, in particular to a wire laser marking device on the fly, a laser marking system and wire production equipment. Background technique [0002] Wire coding refers to marking the outer surface of the wire. Traditional wire coding is through inkjet coding or ordinary laser flying coding. [0003] Ink printing requires the purchase of ink, which requires a large cost of ink consumables, and the overall processing efficiency is not high, causing serious environmental pollution and harm to the human body. [0004] Ordinary laser flight coding, generally using fiber laser flight coding, ultraviolet laser flight coding and CO 2 Laser marking on the fly, optical fiber laser marking on the fly and ultraviolet laser marking on the fly are suitable for wires with few colors and are easy to scratch off. CO 2 Laser coding on the fly is easy to break through the insulation layer on the surface of the wire...

AI Technical Summary

Problems solved by technology

Ordinary laser flying codes are not high in laser frequency and galvanometer coding speed is not high. As a result, when the wire transmission speed is fast, only short character segments can be coded on the fly. If you want to code long character segments, then It is necessary to reduce the transmission speed of the wire, and it is impossible to print long characters under the high-speed transmission of the wire
